Carlos,
This is most likely an alternator problem. I have asked Trevor for information he has about this in the past, as well as Christian at Maniac Electric Motors, in DALLAS.
Trevor said the following and I have confirmed that this has happened in the past on other cars:
The flashing of several dashboard trouble indication lights instantaneously can indicate a rather obscure alternator fault.
The indicator light test circuit, incorporates blocking diodes to eliminate a sneak circuit which would otherwise exist. A fault within the alternator rectifier network, often involving only a single diode, can result in alternating current being induced on line. As a result, pulses of reverse voltage pass the blocking diodes in the circuit which energizes the indicator lights.
Those testing alternators, including professional technicians, can often fail to detect this problem, due to there being only a very small discrepancy in the D.C. output.
Testing battery voltage with a multimeter switched to the alternating current range, will often disclose the presence of the unwanted alternating current, whereas a normal direct current output voltage check will not. An oscilloscope will certainly disclose the problem.
Steady Dash light indication
Steady simultaneous illumination of dash lights (battery charging, steering, and stop lamp) indicates one of several alternator faults, which can be detected by the alternator’s electronic diagnostic module.
It would appear that for safety sake in the event of an alternator fault, those indicator lights which are not illuminated for test purposes at start up, are operated simultaneously.
Personally, I would head over to Maniac Electric Motors in Dallas to have them take a look at your alternator. They have the best test equipment and experience in diagnosing/repairing alternators. They do all of their own rebuilding, and use the best German electronics. No one better at what they do and a new rebuilt alternator should be no more than $88.00 exchange. They also have the electrical plugs if you need them. Christian is the best and they will figure it out.
